Consumer advice
If you want more fiber, this works fine and the label is honest about what it contains. Compare the per-serving price to plain flaxseed meal or acacia powder, which are usually cheaper per gram of fiber if you don't need the pre-mixed convenience. Start with a small amount as directed to avoid bloating, and drink plenty of water.
